Hi Peter,

What's the status of these issues?  Should I test a newer version or
rather shut up and send patches? :)  Another interesting thing (not
sure if I've mentioned already) is that after dismissing the boot:
prompt there is a long delay (order of a minute) before output starts
appearing.  I'll investigate this further, just wondered whether
you'd got an idea.
